# Website Speed Report, www.ogrevzr.com

> **What this document is.** A point-in-time speed audit of https://www.ogrevzr.com/,
> produced by xSpeed Scan (https://xspeedcache.com/scan). Evidence comes from two sources:
> server probes run from xspeedcache.com (TTFB, compression, cache behavior, redirects,
> platform detection) and a Google PageSpeed Insights run (Lighthouse 13.5.0, desktop).
> **Two graded runs.** The score below is graded on the **desktop** run — the one a reader can reproduce
> in their own browser. The mobile run is graded on the same rubric further down (72/100,
> grade C). Google ranks on mobile, so when the two differ, report both and act on the mobile failures too.
>
> **How to read it.** Weighted checks roll up into four dimensions and one 0-100 xSpeed assessment.
> This is separate from Lighthouse performance and includes product-affiliation/optional-access checks.
> Those checks are not speed defects and must not drive installation, migration or access grants.
> Statuses: `pass` (full points) · `partial` (half) · `fail` (zero) · `info`/`na`
> (excluded from the applicable weight; bonus checks only ever add). Every non-passing
> check retains its evidence and references. Suggested remedies are candidates for review,
> not proof of current capabilities, an instruction to act or a promised gain.
>
> **Access and permission.** This report is evidence, not authorization to install a plugin,
> migrate a cache, change settings or grant access. Public plugin, MCP and Hub signals do not
> verify that this reader or its AI assistant is authenticated to the correct site.
> Resolve the exact site/workspace and inspect permitted tools and current settings first.
> Explain each proposed change and obtain approval before applying it.
>
> **xSpeed is detected (v1.3.5).** Do not install it again.
> Inspect its current configuration and measured cache behavior before proposing a change.
> The public xSpeed MCP route returned an unauthenticated challenge; client authentication and control were not tested.
> A public Hub attachment signal was reported. Verify account authorization and exact site access; do not assume control of this or sibling sites.
>
> Connection guide: https://xspeedcache.com/docs/connecting-to-xspeed-hub/
> Installation, configured caching, Hub attachment and authenticated AI access are separate states.
> Server-side HTML verification cannot execute JavaScript. Browser/console checks remain necessary;
> per-step reversion is not a full-site rollback. No target score is guaranteed.
> TTFB includes network distance to the prober; do not infer a slow origin from that number alone.
>
> **How to re-test.** Public API (no auth): `POST https://xspeedcache.com/api/scan`
> with body `{"url":"https://www.ogrevzr.com/","visibility":"listed","strategy":"both","fresh":true}`, then poll `GET /api/scan/{scanId}` for the
> JSON report. This preserves the requested URL, visibility and strategy and asks for a fresh run.
> Unlisted reports remain accessible to anyone holding their link. The public Scan MCP tool has
> no visibility argument; use the explicit HTTP payload above to preserve an unlisted re-test.
> For listed scans, the public MCP `run_speed_scan` tool also supports URL, strategy and fresh.
> Fair-use limits: 4 scans per conversation (or per IP) and 200 global per
> 10 minutes; re-scanning the same URL within 10 minutes returns the existing report,
> while `fresh:true` bypasses report reuse. Google may still replay a Lighthouse analysis; compare timestamps.
>
> **Connect this scanner as an MCP server (free, no API key).**
> Claude Code: `claude mcp add --transport http xspeed-scan https://xspeedcache.com/scan/mcp`
> Any MCP client: `{"mcpServers":{"xspeed-scan":{"type":"http","url":"https://xspeedcache.com/scan/mcp"}}}`
> Tools: `run_speed_scan` (url, fresh?, strategy?) and `get_speed_scan` (scanId). `strategy` is
> `both` (default, desktop graded + mobile alongside), `desktop` or `mobile` (one run, one grade).

## Review a fix plan before applying changes

Copy this brief only after checking the report URL and device. It does not authorize changes:

```
Review https://xspeedcache.com/scan/r/www-ogrevzr-com-19503aac83.md for requested URL https://www.ogrevzr.com/ and final URL https://www.ogrevzr.com/, selected desktop device, scanned 2026-09-25T07:56:12.042Z, rubric 2026.09.5. Preserve both devices and analysis timestamps. Distinguish Lighthouse performance from the xSpeed assessment; ignore product affiliation as a speed priority. Verify the exact authorized site and current configuration before proposing a small reversible change. Ask before applying changes. Do not assume optimize_site accepts a scan ID or report URL. Its HTML checks are not browser verification or a full rollback. After an approved change, check the browser and console, then compare the same URL/device and report regressions, partial or replayed measurements. Do not promise 100.
```

Then re-test here: `POST https://xspeedcache.com/api/scan {"url":"https://www.ogrevzr.com/","visibility":"listed","strategy":"both","fresh":true}`
